MECHANISM FOR ACTUATING ROVING-RODS OF SPINNING-MACHINES.

SPECIFICATION forming part of Letters, Patent No. 527,591, dated October-.16, 1894.

Application fil d March 8, 1894:; Serial No. 502,795. (No model.)

To all whom, it may concern.-

Be it known that I, GEORGE E. CHANDLER,

of Fall River, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Mechanism for Actuating the Roving-Rods of Spinning- Machines; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the ac- (ompanying drawings, forming part of this through which the traverse-rod is actuated that all wear of the bearing parts will be antomatically taken up.

The invention consists in the peculiar construction of the mechanism for exerting a reciprocating motion to the traverse-rod.

The invention also consists in the combination with the traverse-rod and a pin or stud carried thereby, of a lever bearing against this pin, means for holding the pin in place by automatically taking up the wearon the parts, and mechanism for oscillating the lever to reciprocate the traverse-rod.

Figure 1 represents an elevation of the improved actuating-device applied to a spinning-machine, the rolls and their hearingbra'ckets being removed to more clearly show the construction of the compensating or take- 7 Fig. 2 represents a detailed view 7 ciprocating or traversing rod carrying trumpets or guides through which the fiber is guided and delivered to the rolls during the reciprocation of the traverse-rod. If, at in' tervals in its reciprocation, this rod dwells, or is arrested in its movement, it is evident that a greateramount of fiber will be delivered to the rolls than at those points where the motion is uniform, the result of these dwells, whether resulting from back lash at the ends of the strokes, or otherwise, being to subject the corresponding portions of the rolls to greater use and wear than at the other parts of the same, the rolls thus being unevenly worn rendering the rollsiunfit for successful spinning.

In carrying my invention into practice my desire. has been to so construct the device for actuating the traverse-rod that any wear either in the bearings of the actuating-device or of the connection between the actuating-device and the traverse-rod will be antomatically compensated for through the action of the mechanism.

In the drawings 5 indicates the top of a spinning-machine, or of any similar machine,

in which it is necessary to deliver the-fiber along the greater length of rolls, which may be worn thereby. On this top 5 is secured any well-known form of bracket 6 furnished with a lateral-arm 7 having an adjusting-slot 8. In the upper end of the bracket is journaled a shaft 9, generally extending at right angles to the arm 7, and on this shaft are secured the heart-shaped cam 10 and the gear 11, this gear being driven in any usual manner, as bymeans of the worm 12, to rotate the shaft 9.

Adjustably secured in the slot'8 of the arm 7 is the pivot or stud 13 and. on this stud are rotatably mounted the members 14 and 15 together forming a bell-crank lever. The

member 14 has an upwardly-extending arm 16 with a smooth inner surface, and a laterally curving bearing-finger 17 the end of which bears against the edge of the heart-shaped cam. The member 15 has an upwardly-extending arm 18, also with a smooth inner surface, and alaterally-depending lever 19 to the end of which the weight 20 is secured by the wire 21. In the back of this member a socket 22 may also be formed sufficiently Wide to receive the base of the arm 16 and to allow of a certain degree of independent movement between the arms.

The shaft 9 being rotated and the cam 10 h with it, the finger 17 bearing on the edge of the cam will follow its outline, being depressed by the cam as the highest point of the cam is brought nearer to the end of this finger and moving the arm 16 toward the left, this arm bearing on the pin 27 in turn reciprocating the traverse-rod in the same direction. As the highest part of the cam 10 passes the end of the finger 17, the weight 20 is allowed to act on the lever 19 to throw the arm 18 to the right to move the traverse-rod also in that direction. At the same time the arms 16 and 18 form jaws on which a constant closing pressure is exerted. Should, therefore, the pin 27, the inner surface of these arms, the bearings of these arms on the pin 13, or the end of the bearing-finger l7 become worn the arms will automatically close together and take up such wear so that the pin 27 will always be in intimate contact with both, and no space will be left between the pin and the surfaces of the arms which must be traversed by one or the other before the pin is acted upon, as when these arms were rigidly connected. Therefore no dwells in the motion of the traverse-rod will occur.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a spinning or similar machine, the combination with the traverse-rod, and a pin secured thereto, of a pair of jaws formed of independent levers having upwardly-extending arms journaled on a common shaft, each of said levers having a laterally-extending member, a weight secured to one of said members, and mechanism for depressing the other members at intervals.

2. The combination, in a spinning or other machine, with the bracket 6 provided with the arm 7 having the slot 8, the pin or shaft 13 secured in said slot, the member 14. having the arm 16 and finger 17 pivoted on said pin, the member 15 having the arm 18 and the lever 19 also pivoted on the pin 13, and means for alternately depressing the finger 17 and the lever 19, of the traverse-rod 23 mounted in supports provided with guides, and the pin 27 secured to the traverse-rod and adapted to be grasped between the arms 16 and 18, as described. 1
